ABORTPixel Abort Pixel Data Read

Encoding: 0x19: <0001_1001>

ABORTPixel is an optional command that stops a READPixel command during its execution. It also causes pixel

integration to terminate and the device to enter the auto-zero/reset state. Any values that were being held in

the arrays sample/hold circuits are lost.

READHold Sample and Read Combination

Encoding: 0x12: <0001_0010>

READHold is a macro command that combines both the SAMPLEInt and READPixel commands into a single

command.

READHoldNStart Combination

Encoding: 0x16: <0001_0110>

READHold is a macro command that combines the SAMPLEInt, READPixel, and StartInt commands into a

single command. 22 clock cycles are necessary to complete the pixel reset cycle.

The register commands provide the user the capability of setting gain and offset corrections for each of the three

zones of pixels. a4a0 refer to the register address as given in Table 2.

REGWrite Write a Gain/Offset/Mode Register

Encoding (2 bytes): 0x40 : <010a4_a3a2a1a0>

REGWrite writes a value into either a gain, offset, or mode register. The 5-bit address of the register is encoded

into the lower 5 bits of the command byte (the first byte). A second byte, which contains the data to be written,

follows the command byte.

REGRead Read a Gain/Offset/Mode Register

Encoding: 0x60: <011a4_a3a2a1a0>

REGRead reads the value previously stored in a gain, offset, or mode register. The 5-bit address of the register

is encoded into the lower 5 bits of the command byte. Following receipt of the REGRead command, the device

places the contents of the selected register onto the SDOUT pin, LSB first.

There is a 4-clock cycle delay from the completion of the REGRead command until the register contents are

output.
